 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Characterization and Determination of Ethylene Responsive Sensor Genes in Khao Dok Mali 105 (KDML105) Rice During Rice Tungro Bacilliform Virus (Chainat isolate) (RTBVCN) In ผู้เขียน:ญาดา มุขแจ้ง, ปาริชาติ เบิร์นส สื่อสิ่งพิมพ์:pdf AbstractEthylene receptor family including ethylene responsive sensor 1 (Os-ERS1) and ethylene responsive sensor2 (Os-ERS2) were isolated and characterized. Sequence analysis showed that both sequences of Os-ERS1 and Os-ERS2 genes comparing with japonica variety had 99.4 and 98.2 percent identity, respectively. Southern analysis indicated that only one copy of both Os-ERS1 and Os-ERS2 was found in KDML105 rice genome which located on chromosome 3 and 5, respectively. In order to understand signaling system of ethylene in rice plant during Rice Tungro Bacilliform Virus Chainat isolate (RTBVCN) infection, RTBVCN infectious clone was Agrobacterium infiltrated into the meristem of two week old rice plant. Northern analysis was performed to determine the expression of three ethylene receptors (Os-ERS1, Os-ERS2 and Os-ETR1) and four ethylene responsive factors (Os-ERFG1, Os- ERFG2, Os-ERFG3 and Os-ERFG4). The result revealed that the expression of Os-ERS1 and Os-ETR2 are elevated by RTBVCN inoculation, whereas Os-ERS2 is constitutively expressed. In transcriptional regulation step, the expression level of Os-ERFG1 is strongly induced during RTBVCN infection. Os- ERFG1 has been showed to play a major role in plant-pathogen interaction resulting in plant resistance. The result suggests the possible association of ethylene signaling in response to RTBVCN infection. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Sequence Analysis of Ethylene Response Sensor Gene Isolated from Vanda Miss Joaquim Flower ) ผู้เขียน:ดร.นพมาศ โลกคำลือ, ผู้ช่วยศาสตราจารย์ , พัฒนา ศรีฟ้า ฮุนเนอร์ สื่อสิ่งพิมพ์:pdf AbstractA specific ethylene receptor protein is a major key for ethylene perception into plant tissues. Thus, the Ethylene Response Sensor (ERS) gene was isolated from the ethylene-sensitive flowers of Vanda Miss Joaquim and its deduced ethylene response sensor (ERS) was aligned with three other reported orchid ERS genes to identify the specific divergence in orchid ethylene receptor proteins. The results from multiple alignment showed that the amino acid sequence of the Vanda ERS was 95% identical to Phalaenopsis ERS (the ethylene-sensitive species), but shared 90–91% identity with the ERS isolated from two ethylene-insensitive orchid species, Dendrobium hybrid Khao Sanan and Oncidium Gower Ramsey. The most conserved regions were located at the N-terminus of the polypeptide being three transmembrane hydrophobic regions; however, the most variable regions, particularly for the Dendrobium ERS and Oncidium ERS, were located in the ATP-binding site of the histidine kinase domain and the amino acid sequence of the downstream histidine kinase domain at the C-terminus. The findings suggest the sequence similarity in the ATP-binding site can be used to distinguish the closely related ERS proteins. In considering the level of ERS gene expression, there was an abundance of ERS transcript accumulation in fully opened Vanda Miss Joaquim flowers (particularly in the column and the lip followed by the perianth tissue) compared with root and leaf tissues. |
